WebNow we invoke the Kraft-McMillan inequality, so the theoretical codelength for x using Pis logP( x) ˇ logp( x) x(3) bits. This is the compression interpretation of the negative log density: it is a codelength for data discretized to high precision, when added to the total number of bits of discretization precision. It is this codelength, Eq. WebKraft's inequality was published in Kraft (1949). However, Kraft's paper discusses only prefix codes, and attributes the analysis leading to the inequality to Raymond Redheffer. The result was independently discovered in McMillan (1956).
